Abstract

Fabrication process is often disrupted by non–deterministic job, this create a problem in the Pre-Fabrication department schedule because often the manufacture of raw material for non-deterministic job should given priority. This problem also affected by the existing system which is not yet fully developed to solve the problem of optimize rescheduling master line (seen from total makespan time). Ant Colony Optimization (ACO) variant Ant System (AS) was proposed to solve Job Shop Scheduling Problem (JSSP) with the objective to propose the best schedule that give shortest makespan. The algorithm tested to perform scheduling of 5 projects (consist of 10 parts) as the initial job, and another 2 projects (consist of 4 parts) as the non-deterministic job. For the initial job, makespan was 287 days and after the arrival of non-deterministic job, makespan was 362 days compare with the actual manufacturing time (7 project consist of 14 parts) which is ± 511 days

Abstract

The rapid growth of large cities is heavily influenced by the complexity of the functions that run a city or region. Growth is very rapid development in large cities make the need for land and will further increase the value of land. Needs a very high soil have a tendency value of land in major cities increased. It is influenced by growing development in the region or the city. With the increase in land value that occurs is expected to be predicted so that the increase in land value that occurs not hampers the development of the area. While Geographic Information Systems (GIS) or also known as Geographic Information System (GIS), the end - the end is experienced significant development in line with advances in information technology. GIS is a computer-based information system that combines elements of the map (geographical) and information about the map (data attributes) that are designed to obtain, process, manipulate, analyze, demonstrate and display spatial data to complete the planning, process and investigate the problem. So they make a thematic map of land value that describes the amount of land value or the market price and the ground potential of a certain area, which serves as a spatial information (spatial) is Thematic Map Value of Land, as the information value of land in the city of Serang, making requires data of land prices based on market value.

Abstract

Banten Jaya University is a tertiary institution located in Serang City, Banten Province. Which has three faculties including education, computer science and engineering. In a university, information about alumni data is needed, starting from the department, graduation year, place of work and other information related to the alumni. Tracer Study is useful as a link between universities and the business world and industry. The tracer study process at Banten Jaya University is still not optimal, because the data collection is still done manually by distributing questionnaires to alumni and lack of information dissemination to alumni, because it is limited only through social media. This is why the information system Tracer Study is built using the PHP programming language and MySQLi as the database, to collect alumni information. This information system uses web-based technology and the waterfall method in the development. From the results of testing this system is in accordance with the algorithm that was made,users can fill out questionnaires online, see other alumni information, and managing job openings, as well as displaying graphs of alumni who had worked after graduation and the number of graduates each year.

Abstract

Classification of text documents with large amounts will be a job that requires a lot of time, effort and cost of having to read text documents and then categorize them manually, therefore the automatic classification of text documents is needed. The algorithm developed is K-Nearest-Neighbor (KNN), Naïve Bayes, Support Vector Machine (SVM), Decision Tree (DT), Neural Network (NN) and Maximum Entropy. The algorithm used as the object of research is a variation of the Naïve Bayes algorithm, the Naïve Bayes Multivariate Bernoulli and the Naïve Bayes Multinomial. This study discusses whether there are differences between the Algorithms. The Naïve Bayes Multivariate Bernoulli algorithm and the Naïve Bayes Multinomial can be seen from the value of the agreement and the speed of the process of classifying text documents, as well as more information about the process of processing requests that are getting more and more requested. While the highest value using the non-stemming Naïve Bayes Bernoulli method is 71.33%, and the fastest processing time is required using the non-stemming Naïve Bayes method which requires 0.12 seconds processing time.

Abstract

The PUPR Service of Serang Regency is located on Jalan Sama’un Bakri, Lopang, Serang2City, where there are many areas of duty, one part of which is the development section of the development section, which has tasks in road construction. In recording or data collection, road construction still uses Microsoft Excel, so it is not effective because of data loss and data duplication. So we need a new system that can support these activities. With the website-based information system using the PHP programming language, the database used is MySQL and the Waterfall method makes this information system usable anytime and anywhere. The purpose of this study is to design a rural road development information system that can provide information to the government regarding road construction and can monitor the progress of road construction in progress. The community can also see this information without having to come to the PUPR Office of Serang Regency to ask about information on the construction of their village roads that will be built and can report complaints related to road conditions, especially in the Serang district area in the community complaint feature so that it can be immediately followed up by government.

Abstract

Asset management is the management of asset data by grouping assets based on groups or recording assets in detail with the aim of organizing asset data so that they are well organized. Asset management in Serang City Village still uses conventional methods, especially asset management data collection in Sumur Pecung Village where the data collection still has several shortcomings and problems such as not explaining the layout of assets in detail, the layout of the location of assets, causing loss of one of the assets, the existence of duplicate data, lack of detailed information and poor data collection, namely data that is not integrated by inspectorate employees, especially every asset inspection report by inspectorate employees is not the same in writing this report format. This study aims to create an asset management information system by reducing problems that still use conventional methods. The data collection methods used are interviews, observation, and documentation to obtain accurate data. The software development used is the Waterfall model which is part of the System Development Life Cycle (SDLC) with stages of needs analysis, system design, implementation, integration and testing. Business process modeling uses the Unified Modeling Language (UML) with Use Case Diagram models, Activity Diagrams, and Sequence Diagrams. This information system which will later become a webbased application, was built using the Laravel Framework and several programming languages such as PHP, Java Script, CSS and MYSQL database. With this application, it can reduce asset management problems in Sumur Pecung Village in its data collection.

Abstract

Indonesia is a country that has many types of commodities of various kinds of fruit. Based on BPS data, fruit production reached 22 million tons in 2019, an increase of 5% compared to 2018. However, with such a large production volume, most fruit inspection (sorting) processes in Indonesia are still carried out manually by humans. The manual process requires a lot of time and energy resources, is prone to inconsistencies and inaccuracies. With the help of computer vision, the automation process is expected to be able to eliminate manual processes to reduce costs and increase efficiency and accuracy. In this study, the method used is the YOLOv4 algorithm. The algorithm is applied to detect banana ripeness automatically. The algorithm training process is carried out using 369 banana images divided into two classes, and the testing process is carried out on videos captured in real-time. Based on the research results, the best average accuracy rate is 87.6%, and the video processing speed is 5 FPS (frames per second) using a single-GPU architecture. Indonesia merupakan negara yang memiliki banyak jenis komoditi berbagai macam buah-buahan. Berdasarkan data BPS, produksi buah mencapai 22 juta ton pada 2019 atau meningkat 5% dibandingkan 2018. Namun dengan volume produksi sebesar itu, sebagian besar proses pemeriksaan (sorting) buah di Indonesia masih dilakukan secara manual oleh manusia. Proses manual membutuhkan banyak waktu dan sumber daya, rentan terhadap inkonsistensi dan ketidakakuratan. Proses otomatisasi dengan bantuan computer vision diharapkan dapat menghilangkan proses manual sehingga dapat menekan biaya, meningkatkan efisiensi dan akurasi. Dalam penelitian ini, metode yang digunakan adalah algoritma YOLOv4. Algoritma ini diterapkan untuk mendeteksi kematangan pisang secara otomatis. Proses pelatihan algoritma dilakukan dengan menggunakan 369 citra pisang yang dibagi menjadi dua kelas dan proses pengujian dilakukan pada video yang ditangkap secara real time. Berdasarkan hasil penelitian, tingkat akurasi rata-rata terbaik adalah 87,6% dan kecepatan pemrosesan video adalah 5 FPS (frame per seconds) dengan menggunakan arsitektur single-GPU.
